You have to understand where most of the tools you are using are getting their data from - SHOW ENGINE INNODB STATUS and SHOW GLOBAL STATUS. This data simply is not available broken down on a database level inside MySQL.

MySQL 5.5, 5.6 and Percona Server have been doing a great job of improving the diagnostics available to you with features like performance_schema and userstats - but I don't know of any GUI/monitoring tools that are taking advantage yet.

I recommend installing Percona Server, and taking a look at table_statistics:

MONyog v5.5 has Real-Time feature which tells you what’s happening on your MySQL server RIGHT NOW. It details key metrics like top 200 queries, slow queries, databases, locked queries, locking queries, tables, users, hosts and thread states, all of this in real-time as it happens. Information is retrieved from the server every one second. And the best part is that you can get started with real-time with just a click of a button without the overhead of enabling logs.
